Audiometric Profile in Children Attended at an Infant Audiology Outpatient Clinic
Introduction: Hearing is a precondition for the acquisition and development of language. Many children are later identified with hearing loss, which can impair their development.
Objective: To verify the audiometric profile of children attended at an infant audiology outpatient clinic.
Methods: This is a retrospective study in which the analysis of the pure-tone audiometry data of 262 children from 4 to 11 years old was performed. There were analyzed the data of 524 ears that were categorized as follows: normal hearing (hearing thresholds better than 15 dB), conductive hearing loss, sensorineural hearing loss, and mixed hearing loss.
Results: The results showed 344 (65.64%) ears presenting normal hearing, 104 (19.85%) conductive hearing loss, 68 (12.98%) sensorineural hearing loss, and 8 (1.53%) mixed hearing loss. Regarding the degree of hearing loss, 182 (34.74%) ears presented hearing loss, with prevalence of minimal degree in 48 (26.38%) ears. There was no prevalence of hearing impairment comparing right and left ears.
Conclusion: The conductive hearing loss and the minimum degree of hearing loss were the most frequently observed characteristics in the studied subjects.
